Answer:
c = 13
Step-by-step explanation:
2 ways of going about in this problem
1. If you have done enough Pythagorean theorem problems, you might be able to memorize some common right triangle side lengths, such as 3-4-5 or
5-12-13
2. actually using Pythagorean theorem
[tex]a^2+b^2=c^2[/tex], where c is hypotenuse
c = [tex]\sqrt{5^2+12^2}[/tex]
c = [tex]\sqrt{169}[/tex] = 13
